The official website of Shanghai Songjiang shock absorber Group Co., Ltd. introduces to you: threaded type metallic flexible hose in Guangzhou Metro Line 13 project information. Songjiang group provides  threaded type metallic flexible hose products for many urban subway projects across the country, which are mainly used in fire protection systems and HVAC systems.

Introduction to Guangzhou Metro Line 13

Shipai South Station of phase II of Guangzhou Metro Line 13 is located in the west of Huangpu Avenue, Tianhe District, Guangzhou. On the south side is Zhujiang New Town, close to Huacheng square. It is the core of the core area of Guangzhou. The buried depth of the station platform tunnel is nearly 40 meters, and the stratum is relatively complex. The tunnel passes through completely weathered, strongly weathered, moderately weathered and slightly weathered rock layers respectively, so the overall excavation is difficult and risky. In the process of underground tunnel construction, it is very easy to affect the surrounding buildings due to formation water loss, soil disturbance and other factors. In view of the geological conditions of many parts of the tunnel section, the project continues to strengthen the advance geological prediction and analysis of the tunnel surrounding rock.

The construction working surface in the tunnel of Shipai south station is narrow, the construction temperature in the tunnel is more than 38 degrees, and the humidity is high, and the ventilation is difficult. In order to improve the high-temperature working environment, the project department deeply studies the construction scheme and the ventilation design in the tunnel, and finally adopts to install an axial flow fan in the ground and the middle pilot tunnel respectively, which solves the problems of difficult ventilation and high temperature in the tunnel. At the same time, the project department specially purchases an ice maker to transport ice cubes to the tunnel regularly every day for cooling, Create a good construction environment for operators as much as possible.

Threaded type metallic flexible hose is a kind of high quality flexible pipe in modern industrial pipeline. It is mainly composed of bellows, mesh sleeve and joint. The inner pipe of the utility model is a thin-wall stainless steel corrugated pipe with spiral or annular waveform, and the outer layer of the corrugated pipe is a net sleeve. It is an important connecting component in engineering technology, which is separated from corrugated flexible pipe, mesh sleeve and joint. It is used as compensation element, sealing element, connecting element and damping element in various gas transmission and infusion pipeline systems and length, temperature, position and angle compensation systems.
